Final answer:
Tuff is the correct answer to the question as it is a volcanic fragmental rock with a broken structure, formed in the place where it is found.
Step-by-step explanation:
A rock having a broken or breccia structure, which is formed in the place where it is found, is known as tuff. Tuff is a type of volcanic fragmental rock that is formed by explosive eruptions, emitting solid fragments and ash. Among the options given, tuff is the correct answer because it is formed from volcanic activities and is characterized by a light composition that can include ash, glass, and fragments such as pumice. This is seen in the Tumamoc Tuff, which contains fragments of pumice, and possibly biotite and feldspar, indicating it was formed in situ, rather than being transported to its current location like conglomerates or other sedimentary rocks.
Other types of rocks mentioned, such as basalt, are usually igneous rocks that are either extrusive or intrusive. Intrusive igneous rocks like granite are coarse-grained and form from magma that cools slowly beneath the Earth's surface. Conglomerate, on the other hand, is a sedimentary rock composed of rounded, gravel-size clasts that have been cemented together and typically indicate transport from their place of origin.
